Effects of climate on size structure and functioning of aquatic food webs [PDF]

open access: yes, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Estimation of the eddy diffusivity coefficient in a warm monomictic tropical Lake

open access: yesJournal of Limnology, 2016
We used a two-year dataset (1998-1999) of monthly temperature profiles from Lake Alchichica, Mexico to estimate values of the vertical coefficient of eddy diffusivity.

Calculating the sediment budget of a tropical lake in the Blue Nile basin: Lake Tana

open access: yes, 2016
. Soil erosion decreases soil fertility of the uplands and causes siltation of lakes and reservoirs. However, very little data exists to quantify accurately the impact of sediment on lakes in tropical monsoonal areas in the African highlands.

Lake Kivu: Limnology and biogeochemistry of a tropical great lake

open access: yes, 2012
In the heart of Africa, a unique lake has attracted the attention of scientists since the beginning of the 20th century. At the foot of the Virunga volcano chain, Lake Kivu harbors a vast amount of dissolved carbon dioxide and methane, making it the most dangerous lake on Earth.

Sixty years since the creation of Lake Kariba: Thermal and oxygen dynamics in the riverine and lacustrine sub-basins.

open access: yesPLoS ONE, 2019
The current boom of dam construction at low latitudes endangers the integrity and function of major tropical river systems. A deeper understanding of the physical and chemical functioning of tropical reservoirs is essential to mitigate dam-related ...

Drivers for ecosystem respiration during the drawdown period in Dongting Lake, China

open access: yesFrontiers in Environmental Science, 2023
Global lakes play an active role in releasing carbon into the atmosphere. However, previous research was less focused on shallow tropical and sub-tropical lakes, especially ecosystem respiration during the drawdown period.

Review of river fisheries valuation in West and Central Africa [PDF]

open access: yes, 2008
This paper provides a review of the valuation of river fisheries in West and Central Africa. It is the general perception that, compared to the biological and ecological aspects of river fisheries, this particular subject area has received relatively ...

Lyophilisation of influenza, rabies and Marburg lentiviral pseudotype viruses for the development and distribution of a neutralisation-assay based diagnostic kit [PDF]

open access: yes, 2014
Pseudotype viruses (PVs) are chimeric, replication-deficient virions that mimic wild-type virus entry mechanisms and can be safely employed in neutralisation assays, bypassing the need for high biosafety requirements and performing comparably to ...

Additions to the bryophyte flora of Réunion (East African Islands) [PDF]

open access: yes, 2000
Nineteen species of bryophytes are reported for the first time for Réunion. Especially remarkable are the first African record of Anastrophyllum leucocephalum (Tayl.) Steph. and the first records for the East African Islands of Cephaloziella cf. vaginans

Late Pliocene lakes and soils: a data-model comparison for the analysis of climate feedbacks in a warmer world [PDF]

open access: yes, 2013
Based on a synthesis of geological data we have reconstructed the global distribution of Late Pliocene soils and lakes which are then used as boundary conditions in a series of model experiments using the Hadley Centre General Circulation Model (HadCM3 ...
